Chinese geothermal energy survey
China is situated at Asian-European, Indian and the Pacific Ocean crustall plate’s connection, the compound region. Nearby the crustal motion intense structure belt, forms our country geothermal energy the centralized distribution area.
After the general survey, the nation had discovered that geothermal field more than 270, hot spot more than 2500, the geothermal resource concentrates. Looked from the development use’s angle that the geothermal energy is mainly the natural vapor and the geothermal water, generally the name 25-60? hot water the low temperature hot water, 60-100? for the warm hot water, 100? above for high temperature hot water. Geothermal water many by form appearing surfaces and so on hot spring, hot spring, boiling spring, steam spring, eruptive fountain. South the Qinghai-Tibet Plain the Yarlung Zangbo River basin to Yunnan west area Tengchung, is our country mainland high temperature geothermal activity most intense region, the distribution has the big calorimetry spring, the boiling spring, the eruptive fountain and the gas escape and so on, take Lhasa as in the central 280,000 square kilometers scopes, the geothermal resource is rich, the geothermal water leaves the dew point to amount to 116. Yangbajain – damxung – valley dew – Naqu, the Sangri – cona, Bowo – Medog is 3 high temperature geothermal water mobile belt, the geothermal water maximum temperature may reach 93?. The Yunnan Province geothermal resource mainly distributes around Yunnan pond, the Erhai north and south and the Nujiang basin, what is most famous is the Tengchung crater hot spring group, in more than 50 hot spring, 90? above amounts to 9, other also in 50? above.
South Guangdong, Fujian and Hunan, area Jiangxi’s southeast coast is my guozhong low temperature hot spring most crowded region, the hot spring water temperature mostly is 40-80?, minority in 80? above. If Guangdong Province has found the hot water to leave dew point more than 300, 80-103? the high temperature hot water accounts for 6.3%; 40-80? the low temperature hot water accounts for 67%; Other are the low temperature hot water. Geothermal heat pump.
Taiwan tropics go through vertically Taiwan north and south, places such as Hsinchu, Taichung, Tainan have many hot spring appearing, at present had discovered that has more than 100, the water temperature surpasses 100? has 6, other also surpass 60?.
The Northeast area’s geothermal resource concentrates in the Liaodong Peninsula and the Changbai Mountain area, the Liaodong Peninsula geothermal resource with this area break growth related, the Changbai Mountain area concerns with this place’s magmatic activity such as heat pump.
In addition, the Shandong Peninsula, Mt. Taihang, the Luliang, the Weihe River valley land, north the Sichuan basin edge and Tianshan east east the foothill, the Qaidam Basin, Qilian Mountain, the western Hunan, Guizhou Province and so on mountainous areas, have many hot spring appearing, the water temperature are situated between majority of 25-60? between.
The Jiangxi Mt. Lushan’s planetesimal hot spring, Anhui Mt. Huangshan’s hot spring, Shanxi Lintong’s Hua Qing the pond, the Sichuan Chongqing’s north and south hot spring, the Shandong Linyi’s prescription hot spring, the Guangdong Conghua hot spring and Beijing’s Xiaotangshan hot spring and so on, is our country famous hot spring. The heat energy’s use trend looked that besides takes a bath, the medical service, but also uses in generating electricity, warming up, the development fish breeding and poultry raising, the crop production, to grow seedlings Industry sectors and so on seed selection, greenhouse to produce and to use in spinning and weaving, leather making.
